Table 3 Ferritin concentrations in Caco-2 cells exposed to samples of PM only and PM-based diets

From: Higher iron pearl millet (Pennisetum glaucum L.) provides more absorbable iron that is limited by increased polyphenolic content

Tested sample 1

Ferritin/cell protein (ng/mg)

Cell Baseline2

FeCl3

58.69b ± 2.29

FeCl3 + Ascorbic Acid

364.95a ± 19.55

Low-Fe PM only

1.22e ± 0.05

High-Fe PM only

2.61c ± 0.36

Low-Fe PM-based diet

1.47de ± 0.27

High-Fe PM- based diet

2.46c ± 0.13

  1. 1Caco-2 bioassay procedures and preparation of the digested samples are described in the materials and methods sections (mean ± SEM).
  2. 2Cells were exposed to only MEM (minimal essential media) without added food digests and Fe (n = 6).
  3. a-e Within a column, means without a common letter are significantly different (P < 0.05).
